Nothing is True...

Sailing to Tulum is no easy feat. The waters are filled with dangerous foes and several forts block the way. Take the time to plunder any and all ships and upgrade the Jackdaw. Take down the forts near Tulum for easier access and to clear the waters of enemies. Once you reach Tulum, the mission begins with Edward on the beach.

LOOT TREASURE CHEST (1 OF 4): But before you do anything, make a 180-turn and look behind the large rock to find the first treasure chest to loot. To find the other three chests, you'll need to Synchronize the island.

KNOCK OUT ASSASSINS: Swim towards the next beachside area with bushes and climb up and hide. There will be THREE Assassins that patrol this area (one roaming, two stationary). Wait for the roaming Assassin to move away and then choke out the first guy in front of you (no need to whistle him in).

With the first Assassin down, quickly approach the roaming Assassin and knock them out.

The third Assassin is just up the path in front of a haystack, quickly jump into that haystack and knock out the third guy to complete the objective.

From here, do NOT go to the other side of the beach just yet! Across from the haystack is a higher cliff ledge with a Viewpoint. Quietly make your way up the cliffside and hide in the bushes to see TWO Assassins guarding the Viewpoint.

Take down both Assassin with stealth and then climb up the wooden mast to the Viewpoint and Synchronize the beachside. From there, the remaining three treasure chests will be revealed on the GPS map.

With the beachside Synchronized, dive down to the water (or to the haystack) and use the bushes from the back of the area. Since most of the Assassins on the beach are facing the water, you'll have to sneak behind them.

Make your way towards the waypoint and wait for the Assassin to turn around and then run up and smack him. BUT WAIT!

LOOT TREASURE CHEST (2 OF 4): Before you leave the area, there is another treasure chest! The chest is at the other end of the beach and has an Assassin guarding it. Wait for the Assassin to turn around and then run up and smack him. Now open the chest.

Once that's done, enter the next area to the jungle. There is NO need to eliminate anybody in this area, so avoid combat! Run towards the sculpture and climb up towards the branches.

Go to the LEFT side of the jungle and scale down the tree to the bushes next to the stairs. Rotate the camera to watch the roaming Assassins below! When the coast is clear, run up the stairs towards the next sculpture.

Climb the sculpture and jump towards the tree watchtower. The waypoint is to the left side, so jump towards that direction and jump down to the path below. Be quick so that the Assassins don't spot you!

The third area is a large Mayan ruin. There are numerous Assassins roaming the lower area, so avoid sneaking the lower area.

Make a left turn at the stairs and quickly climb it up to the top and then hide in the bushes. There are FOUR Assassins and a treasure chest in this section.

LOOT TREASURE CHEST (3 OF 4): Quietly knock out all four of the Assassin guards to clear the area. From there, approach the lone chest at the back and open it up.

At the edge of the cliff, jump towards the Mayan ruin and climb it to the top. Hide in the bushes and look forward to see two more Assassins. Knock them both out to clear the top area.

To reach the last waypoint at the very top of the ruins, jump towards the large tree branches (watch out for the sniper) and towards the sniper. Knock out the sniper and then hide in the bushes nearby.

When the coast is clear, take the path to the right side and then go up towards where James Kidd is waiting BUT WAIT!!!

LOOT TREASURE CHEST (4 OF 4): Before you speak with Kidd, there is ONE more treasure chest to loot! Across from where Kidd is standing is another Mayan ruin. Make your way towards the ruin and find the last treasure chest on the right side. And while you're there, solve the Mayan Stelae puzzle.
